Hydraulic Cylinder Linear Position Sensor

In cylinder linear displacement transducers ldts have been used with limited success in mobile equipment to achieve these goals.

Hydraulic cylinder linear position sensor.

The cable connector installs into the piston or rod via a 7 16 20 threaded connector and the sensor is coupled to the cylinder via a hydraulic hose through a. Position sensing smart hydraulic cylinders internal ldt. The ss 7 series lvit linear variable inductance transducer position sensors from alliance sensors group have been designed to give cylinder position feedback in subsea environments with depths up to 12 000 ft or in a pbof pressure balanced oil filled chamber for oil and gas exploration blow out preventers rovs and relief valves. Cpi s hydraulic cylinder position sensors install into standard hydraulic cylinders with minimal modifications and are suitable for field retrofit where rod type sensors have failed.

A limitation to most in cylinder ldts is that the hydraulic cylinder s piston rod must be bored through its center to accommodate certain elements of the ldt usually the waveguide tube of a. Special spacers are available to alter the probe length for specific applications. These sensors are also atex and iec ex intrinsic safety rated and support stroke lengths up to 30 meters. Each sensor mounts into the standard in port cylinder position sensor bolt pattern.

The mr 7 series lvit linear variable inductance transducer position sensors from alliance sensors group has been designed as an alternative to magnetostrictive sensors and has more robust construction and a lower cost of ownership.
